Datetime - Creating A Date From A Text String?
Sep 20, 2009
I having a problem converting a string into the date format I need. An example of the string I'm trying to convert would be 215056081909. I would like to convert that string into 08/19/09 21:50:56.The code listed below is what I'm trying to use for the conversion process. When I run the code I'm getting the error below and I'm pretty sure it's because my string has the time portion in military (24 hour) time.
Error:
System.ArgumentOutOfRangeException was unhandled
Message="Index and length must refer to a location within the string. Parameter name: length"
ParamName="length"
[code]....

I am located in the NorthEast US. My problem is properly storing a string in European date format (today is 23/1/2012).
For example the string '12/1/2012' is stored as as December 1, 2012 not January 12, 2012.
How can I dimension a DateTime variable to store the European date string properly?

When I looked at the database record, the datetime saves like this: 4/6/2012 04:42:28 PM
because I've save it using dbtype.string
Now, I'm getting the date only, not including time, this is my code:
Private Sub getpapererror(ByVal ddate As String)
Dim sqlstr As String = "select * from perror where date(ddate) = $xddate"
Dim sqlcmd As New SQLiteCommand(sqlstr, mycon)
[Code].....

how I can ensure that conversion of a date to a string and a string to a date will give me the same date format.
For example:
Code:
Private Sub Button1_Click(sender As System.Object, e As System.EventArgs) Handles Button1.Click
Dim d As Date = Date.Now
[code].....
I'm actually only interested in the date part as the label text shows so f is more than I want.But also, the day and month are reversed.

I just want everything to line up nicely. Would I need to make my own function to do this or is there a way with string.format or regex?

the last date was saved on database is: 6/13/2012 12:27:30 PM
In my DateTime Now is:6/13/2012 01:27:57 AM
but, when I execute this function, it always say:"Date has been manually modified, Please Set to Valid DateTime" But, DateTime Now is NOT lessthan the Date from my Database. What's wrong?
This is the code, please correct it,

From what I can tell Date and DateTime have the same functionality. Is there a reason why I would want to use one instead of the other?

1. Write a Visual Basic Console Application which creates two DateTime objects. One DateTime object should be used to store a value for date purchased. The second DateTime object should be used to store a value for date paid. See below for more information.
2. Assign values to the two DateTime objects.
3. Use the toString method to display the two DateTime objects.
4. Compare the two dates to determine which date occurred first.
5. Compute the number of days elapsed between the two dates.
6. If the date purchased occurred before the date paid, display: The number of days required to receive payment was ________. Replace the _________ with the number of days computed between the two dates.
On the other hand, if the date paid occurred before the date purchased, display: The number of days this order was pre-paid was _______. Replace the _________ with the number of days computed between the two dates.
If the two dates are identical, display: The payment was received on the same date as the purchase.

I want to insert only date into the db but in the following statement that I've wrote which inserts the date in mm-dd-yyyy hh:mm:ss format.
InsertCmd = "Insert into Blotter (Name, Product, Date_Time) values ('" & NameLabel.Text.Trim() & "','" & ProductTextBox.Text.Trim() & "','" & TimeLabel.Text.Trim() & "')" & "Update Blotter Set Name = UPPER(Name)"
I have tried the following code, however it didn't work.
InsertCmd = "Insert into Blotter (Name, Product, Date_Time) values ('" & NameLabel.Text.Trim() & "','" & ProductTextBox.Text.Trim() & "','" & (CDate(TimeLabel.Text.Trim().ToString("MM/dd/yyyy")))& "')" & "Update Blotter Set Name = UPPER(Name)"
[code]
I also tried format the TimeLabel as below but still didn't work. [code] TimeLabel.Text = CDate(DateTime.Now).ToString("MM/dd/yyy")

I'm pulling into a variable a datetime value. Now, I want to post this value back to my database, but I need it to be only the year digits. How do I get VB.NET to trim the month, day, and time off and just return the four character year (e.g. 2011)?
